Extra material for cuts, spillage and breakage.

- Linear feet off the roll
- 16.5ft
- Padding

How this is calculated
square yards = (area + waste) ÷ 9; linear feet = (area + waste) ÷ roll width
- Carpet is sold by the square yard, which is 9 ft².
- Broadloom comes off a fixed-width roll, so a room narrower than the roll still consumes the full width — the linear-feet figure is what you are actually billed for.
- Seam placement and pile direction can push real usage above this; a fitter measuring on site will confirm.
- Padding is quoted at bare floor area, without the waste factor.
Häufig gestellte Fragen
How does the Carpet Calculator work?
It applies the formula square yards = (area + waste) ÷ 9; linear feet = (area + waste) ÷ roll width. Enter your measurements and the result updates instantly in your browser — nothing is uploaded and no sign-up is needed.
Why should I include a waste allowance?
Offcuts, spillage, breakage and an uneven sub-base all consume material that the raw geometry does not account for. The default allowance is deliberately modest; increase it for complex layouts, and remember that running short usually costs more in a second delivery than the surplus did.
Are the results exact?
They are a close estimate, not a guarantee. Carpet is sold by the square yard, which is 9 ft². Real materials vary by supplier, moisture content and compaction, so confirm the rate with your supplier before placing a large order.
Is this tool free?
Yes, completely free with no registration. All calculations happen client-side in your browser.
Does it work on mobile?
Yes. The calculator is fully responsive and works on phones and tablets in any modern browser — useful when you are measuring on site.

About the Carpet Calculator
The Carpet Calculator converts a room into the square yards carpet is priced by, and the linear feet you are actually billed for off a fixed-width roll. Enter your measurements and the result updates as you type — there is nothing to submit and nothing to wait for.
Everything runs in your browser. Nothing you enter is sent to a server, there is no sign-up, and there is no usage limit.
Who it's for
Anyone pricing a carpet job before calling a fitter.
How the calculation works
square yards = (area + waste) ÷ 9; linear feet = (area + waste) ÷ roll width
The result depends on a few standard constants, which are stated on the page rather than hidden:
- Carpet is sold by the square yard, which is 9 ft².
- Broadloom comes off a fixed-width roll, so a room narrower than the roll still consumes the full width — the linear-feet figure is what you are actually billed for.
- Seam placement and pile direction can push real usage above this; a fitter measuring on site will confirm.
- Padding is quoted at bare floor area, without the waste factor.
Getting an accurate estimate
Measure twice. Small errors in a linear dimension compound, because material volume scales with two or three of them at once — a 6-inch error across a 20-foot run is over a cubic foot of material on a 4-inch pour.
Keep the waste allowance. The default is deliberately conservative: offcuts, spillage, uneven sub-base and breakage are all real, and running short mid-job usually costs more in a second delivery than the surplus did.
Round up when you order. Suppliers sell in fixed increments — quarter yards, whole bags, full boxes — so treat the figure here as the minimum you need rather than the exact amount to buy.
